The given question is incomplete. The complete question is:
Elemental S reacts with gas to form gas according to the reaction depicted here.
Before a chemical equation can be used to conduct stoichiometric analysis, it must balanced. Type the balanced chemical equation for this reaction between solid sulfur and oxygen gas.
Express your answer as a chemical equation including phases.
Answer:
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas. Liquids are represented by (l) and gases are represented by (g).
The balanced chemical reaction will be:
The Environmental Protection Agency suggests using cold tap water for cooking instead of starting with warm tap water is because our drinking water is made out lead pipes, which is a serious risk to health.
Explanation:
- Lead is found throughout the environment in lead found in paint, air, soil, food and water.
- Lead can pose a significant risk to your health if too much of it enters your body.
- Lead enters drinking water primarily as a result of the corrosion.
- It also contains in materials containing lead like in the water distribution system and household plumbing.
- Lead in drinking rarely cause of lead poisoning can significantly increase a person’s total lead exposure.
- In particular the exposure of infants who drink baby formulas and concentrated juices that are mixed with water.
- EPA estimates that drinking water can make up to 20% or more of a person’s total exposure to lead which is dangerous.
